At Coherent, we have many years of experience working with laser applications in microelectronics manufacturing. We categorize the applications where our lasers play a role into four (4) areas:

Flat Panel Displays: This area encompasses laser applications used to produce mobile screens and TVs.

Advanced Packaging and Interconnects (API): This area refers to back-end semiconductor manufacturing applications all the way up to printed circuit board (PCB) applications.

Flat Panel Displays (FPD) have become the focal point of today’s mobile communication, as well as personal computing up to the 3D TV experience. Coherent provides laser-based solutions for a wide range of applications for the FPD industry, including the production of Low Temperature Poly-Silicon (LTPS) essential for the Thin Film Transitor (TFT) backplane of advanced LCD and OLED displays, cutting glass and foils, direct laser patterning, marking, engraving, welding, and many more. As the world's largest supplier of lasers, Coherent offers state-of-the-art laser systems from the UV to IR. For selected applications, Coherent provides optimized beam delivery systems that support the wide range of laser applications in the FPD industry.

Coherent lasers are designed to operate in industrial environments with the highest reliability and lowest cost of operation. In addition to this, Coherent is actively involved with key industry leaders in developing customized, leading-edge solutions in its world-class laser processing centers.

In front-end semiconductor manufacturing, lasers are mainly used in two applications: in lithography tools and in inspection. There are many different inspection steps in a modern semiconductor lab and Coherent lasers are used in most of them: mask inspection, bare and patterned wafer inspection, etc. Coherent has many years of experience building lasers for these very demanding applications, which require ultra-high precision and no unscheduled down time.
